Data Purshase

I bought a once off data bundle. The amount charged is immediately added to my account - Contract customer - and Vodacom does not allocate the data. How difficult is it to allocate data charged for? Why must one wait up to 24 hours for data allocation? It is pretty pointless then if you have to wait so long. Can someone please allocated the ****** data I bought. Seriously. I have called 3 times already. It would happen within the hour. Still waiting.
